Specialty Lubricants for the Cement Industry

Vertical mills are commonly used for raw material and cement grinding. In terms of lubrication, the most critical parts of vertical mills are the bearings of the grinding rollers, the separator bearings and the gearbox. The bearings of the grinding rollers are exposed to extremely high vibrations (short time overloads), elevated tempera­ ...

Basics of Vibration Measurement - Inst Tools

Vibration is the oscillation, or moving back and forth of an object. The word vibrations consciously or unconsciously use it as a measure of how well things are running. For vibration to get start it takes some effort, either external or internal to get vibration going, some input of energy through an applied force.
